The Quantum Characters of Two-level-atom to the Cavity Optomechanical system

Abstract

With the widely application and development of the mechanical system and optical microcavity, the strong coupling between mirror and cavityfield in the system of cavity optomechanics,that make the optomechanical system become an important platform which is used to inspect macroscopic quantum phenomena and text quantum theory, so that become a new research hot spot.At the same time,for cavity opto-mechanics,there are important application prospect in gravitational waves detection, infinitesimal is placement and the precision measurement of the quality and so on,therefore the study of cavity opto-mechanics has the profound significance. This article first introduced the optical mechanical cavity, and then examines the atomic population is poor. We found that the difference of atomic population with the time evolution law of motion state of the mirror is very sensitive, if the initial state of the mirror as the coherent state, the atomic population difference will collapse and reply phenomenon, collapse time and cycle depends on the cavity photon number and average number of vibrator. Finally studied the optical mechanical two-level atomic emission spectrum characteristics of cavity.
